Hi,
if i want to assign a normal to a triangle,then,
glBegin(GL_TRIANGLES);
for (i = 0; i < 20; i++) {
glNormal(normals[i]);
glVertex3fv(&vdata[tindices[i][0]] [0]);
glVertex3fv(&vdata[tindices[i][1]] [0]);
glVertex3fv(&vdata[tindices[i][2]] [0]);
}
glEnd();
and,if i want use indexd array,then i have to have normals array with same size as vertices array!I have a little confused,are these normals redundant ??
